As of November 23, 2015, 19 people in seven states have been reported to be infected with a strain of E coli that has been linked to chicken salad sold at Costco, the US Centers for Disease Control and Prevention reported Tuesday. The strain is known as known as Shiga toxin-producing Escherichia coli O157:H7 (STEC O157:H7).
Five have been hospitalized, and 2 have developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported, the CDC said.
Evidence available at this time suggests that rotisserie chicken salad made and sold in Costco Wholesale stores in several states is a likely source of this outbreak.
Fourteen of 16 people purchased or ate rotisserie chicken salad from Costco in the week before illness started.
The ongoing investigation has not identified what specific ingredient in the chicken salad is linked to illness.
Costco reported to public health officials that the company had removed all remaining rotisserie chicken salad from all stores in the U.S. and stopped further production of the product until further notice.
Consumers who purchased rotisserie chicken salad from any Costco store in the United States on or before November 20, 2015, should not eat it and should throw it away.
Even if some of the rotisserie chicken salad has been eaten and no one has gotten sick, throw the rest of the product away.
This product has a typical shelf life of 3 days and is labeled “Chicken Salad made with Rotisserie Chicken” with item number 37719 on the label.
